Waning Gibbous on . The illuminated surface of the moon is 75% and getting smaller. The lunar cycle is 19 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing first ∠4° of ♉ Taurus tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 22 August 2021 at 12:02.
Next Full Moon is the Harvest Moon of September 2021 after 24 days on 20 September 2021 at 23:55.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1782" and ∠1899".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 267 of Meeus index or 1220 from Brown series.
The length of this lunation is 29 days, 11 hours and 2 minutes and it is 48 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠264.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠297.8°.
10 days since point of perigee on 17 August 2021 at 09:23 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 30 August 2021 at 02:22 in ♊ Gemini.
The Moon is 402 222 km (249 929 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 100 km (251 096 mi).
10 days after descending node on 16 August 2021 at 16:04 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 August 2021 at 05:13 in ♊ Gemini.
8 days since the last southern standstill on 18 August 2021 at 22:24 in ♑ Capricorn when the Moon has reached South declination of ∠-25.761° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠25.868° at the point of next northern standstill on 2 September 2021 at 00:23 in ♋ Cancer.
24 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.
In 10 days on 7 September 2021 at 00:52 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
